Revenue leakage is work you've already done that never turns into revenue: a stop serviced but not invoiced, chemicals added but not charged, a rate increase you meant to apply two seasons ago and never implemented. In a pool service business, this rarely feels like a crisis — it's a few dollars per stop. But a valuation is built on your documented earnings, and leakage suppresses the number buyers apply a multiple to. That makes it one of the most expensive issues a buyer will count against you in a sale.
What is revenue leakage in a pool service business?
Leakage is the gap between the revenue your operation should generate and the revenue that actually reaches your books. Common sources include chemicals and consumables used on-site but never billed, extra services (filter cleans, minor repairs, extra visits) performed as goodwill and never charged, accounts still paying last year's rate, and missed billings when a route changes hands. Individually each is small. Across hundreds of stops, every week, for a full year, the total is revenue you earned but can’t show a buyer.
How does leakage show up in a valuation?
A valuation applies a multiple to a specific financial metric — typically Monthly Recurring Revenue (MRR) for smaller pool service businesses, or adjusted EBITDA as revenue scales. Leakage works against you either way. If your business is priced on MRR, revenue that never reaches your books doesn't just get diluted — it's absent from the number being multiplied entirely. If you're priced on adjusted EBITDA, uncollected dollars lower the figure directly, and because chemical costs are one of the few large variable expenses in this business, unbilled product also compresses gross margin (revenue minus Cost of Goods Sold) — one of the first things a buyer scrutinizes. A lower adjusted EBITDA, multiplied by a lower multiple due to weaker margins, compounds into a materially lower price.
Note: EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. "Adjusted" means certain owner-specific or one-time items have been added back to better reflect the true earning power of the business under new ownership
Unbilled chemicals: a cash cost, not just a lost sale
Chemicals are a pass-through cost that should be recovered in what you charge. Because they're one of the largest variable costs in a pool service business, unbilled product is often the single highest-dollar-value leak an operator can close. The businesses that command the strongest multiples treat chemical usage as a line that ties to billing — product used is product charged. A buyer reviewing your financials can tell the difference between an operation that recovers its consumables and one that quietly eats them, and prices the risk accordingly.
How buyers treat leakage during diligence
Buyers don't just want a high number — they want a number they can trust and repeat. Inconsistent billing reduces what buyers are willing to pay — revenue that was never billed can't be counted. The opposite is also true: an operation where every stop, every service, and every chemical charge is captured and billed reads as lower-risk — and buyers pay more for revenue they can trust. Clean, complete billing isn't just more revenue — it's a more credible number for a buyer to price.
Closing the gap before a sale
The fix is systematic, not heroic. Bill every stop and every service on a consistent schedule, track chemical usage against accounts so nothing goes out uncharged, keep a documented rate card and make sure to apply increases, and reconcile billing against services delivered so skipped charges surface fast. With enough lead time before a sale, this doesn't just tidy the books — it lifts the revenue and earnings metrics a buyer values — and because it's documented, a buyer doesn't have to take your word for it. The earlier you close the leaks, the more of that improvement shows up in your history when it counts.
